How often should the stamping oil of high speed precision punching machine be replaced?

How to replace stamping die oil for high speed precision punching machine:

1. Estimated oil change method. It is based on the experience of the maintenance personnel and the estimated changes in the basic conditions of the oil - such as the oil turning black, smelling bad, turning milky white, etc., to decide whether to change the oil.

2. Timely oil change method. According to the environmental conditions of the place where the high-speed punching machine is located, the working conditions and the oil change cycle of the commonly used refined oil, it will be replaced when the time expires. This method is very useful for companies with more hydraulic machinery.

3. Sampling test method. Sampling and testing the oil in the four-column hydraulic press on time, measuring the necessary new items (such as viscosity, acid value, water content, particle size and composition and corrosion, etc.) and index values, according to the specific measurement values and requirements of the oil Carry out comparison with the oil deterioration standard to determine whether the oil should be replaced. Sampling time: The hydraulic transmission system of general construction machinery and equipment should be carried out one week before the oil change cycle. The hydraulic transmission system of major equipment, such as: TBM full-section roadheader, etc., should be sampled and tested every 500 hours. The test results The technical file of machinery and equipment should be filled in. The sampling test method is suitable for major equipment and large and medium-sized hydraulic machinery.

Generally speaking, the 500 ton high speed press equipment needs to replace the hydraulic oil after 3 months, and then the hydraulic oil needs to be replaced or filtered every 6 months. Remove the residue and waste during filtration. After filtration, it is recommended to add hydraulic oil preservatives, so that the viscosity and wetting properties of the old hydraulic oil can meet the standard.
